For example, the IPTV user ID after the renewal can be as shown in Table 1 with the corresponding relation of binding SNS user ID and binding IP TV user ID.Optionally, the sign that IPTV user ID and mapping relations between binding SNS user ID and the binding IP TV user ID can concern by different relationship map value Friendship Mapping Value, in a single day this good friend's relationship map value just generates and no longer changes, and concerns unless remove the good friend.Wherein, IMPI is that IPTV user ID, UserID are binding SNS user ID.

Table one:

The S211:IPTV server receives the IPTV program acquisition request that the IPTV terminal sends, and carries the IPTV program identification of described IPTV program in the described request;

In the present embodiment, IPTV user can select the interface according to the IPTV program of IPTV system, the IPTV program of selecting it to watch, when IPTV user when this IPTV program selects to have selected in interface IPTV program that it wants to watch, can send the request of IPTV program acquisition to the IPTV server by the used IPTV terminal of this IPTV user, carry the IPTV program identification of described IPTV program in the described request.

S212:SNS user sends the IPTV program by the SNS terminal to the IPTV server and jointly watches request;

Concrete, this IPTV program is jointly watched and is carried SNS user ID and IPTV user ID in the request, this SNS user ID is used for the expression request and carries out the SNS user that the IPTV program is watched jointly, and this IPTV user ID is used for the IPTV user that the IPTV program is being watched in expression;

In the present embodiment, this IPTV program is watched request jointly, is used for SNS user and asks this IPTV user to watch that jointly this IPTV user is watching the IPTV program.This IPTV program watches jointly and carries SNS user ID and IPTV user ID in the request that this SNS user ID is used for the expression request and carries out the SNS user that the IPTV program is watched jointly, the IPTV user that this IPTV user ID is being watched the IPTV program for expression.

Optionally, SNS user need at first login the SNS community system.Concrete, SNS user carries the SNS user ID by sending logging request to the SNS server in this logging request, and the SNS server confirms that according to this SNS user ID this SNS user is validated user.Then send the IPTV program by SNS user to this SNS server and jointly watch request, this IPTV program watches that jointly carrying IPTV user ID and the request of watching the IPTV program in the request carries out the SNS user ID that the IPTV program is watched SNS user jointly; , transmit this SNS user's IPTV program to this IPTV server and jointly watch request according to this ITPV user ID by the SNS server.

Optionally, consider that the user with SNS user identity may also have the IPTV user identity simultaneously, therefore when the SNS user in this step has the IPTV user identity simultaneously, SNS user also can be by IPTV account number cipher login SNS server, by the SNS server in the IPTV User Identity corresponding relation that preserve this locality, whether whether it is legal to inquire about this IPTV user identity, perhaps legal by this IPTV user's of SNS server request IPTV server authentication identity.When this IPTV user identity is legal, then allow the user with IPTV user's account login SNS server.

The S213:IPTV server receives the IPTV program of SNS user's transmission and jointly watches request.

Whether comprise described SNS user ID in binding SNS user ID corresponding to the described IPTV user ID of S214:IPTV server lookup; If comprise, then carry out S215.

In the present embodiment, the IPTV server can be by the corresponding relation of the local IPTV user ID of preserving of inquiry with binding SNS user ID, obtain binding SNS user ID corresponding to described IPTV user ID, thereby judge in the binding SNS user ID of described correspondence whether comprise described SNS user ID.

The S215:IPTV server is according to described IPTV user ID, send the IPTV program to IPTV user and jointly watch request, described IPTV program is jointly watched and is carried described SNS user ID in the request, makes described IPTV user determine whether jointly to watch described IPTV program with described SNS user according to described SNS user ID.

S216:IPTV user receives and responds described program by its place terminal and jointly watches request;

In the present embodiment, when IPTV user disagrees with that the SNS user who represents with described SNS user ID watches its current IPTV program of watching together, then this IPTV user sends refusal by its described terminal IPTV server and jointly watches the IPTV program response, and send the IPTV program by the IPTV server to this SNS user and watch jointly and obtain failure response that this flow process finishes; If when this IPTV user agreed that the SNS user who represents with described SNS user ID watches its current IPTV program of watching together, then this IPTV user sent to the IPTV server and agrees jointly to watch the IPTV program response, and continued to carry out following steps.

The S217:IPTV server receives the agreement of IPTV user's transmission and jointly watches the IPTV program response;

It is pointed out that step S215-S217 is optional, also can not solicit IPTV user's suggestion and directly carry out following steps.

S218: send described IPTV program to described SNS terminal.

In the present embodiment, but also the IPTV program of the described SNS user's transmission of subtend is encrypted, and in one embodiment, it is as follows to encrypt the concrete generating mode of required key:

Preferably, can generate shared key by common authentication manufacturing basis facility (General Bootstrapping Architecture, GBA) request and SNS user place terminal by the IPTV server, generate shared key SNS_key by GBA.This SNS_key can be by the symmetric key between IPTV server and the GBA (Share_key), SNS user terminal unique identification (Terminal Unique ID), the common generation of random number (Rand).Here, symmetric key Share_key is the key that is used for mutual identification between the two (being IPTV server and GBA) that is generated by IPTV server and GBA, the terminal unique identification then is used for terminal of unique identification, international Mobile Equipment identification code (International Mobile Equipment Identity, IMEI) such as portable terminals such as mobile phones.

It will be understood by those skilled in the art that above-mentioned GBA can with the IPTV server disposition on same equipment, also can be deployed on the distinct device.

After GBA generates shared key SNS_key, return response to the IPTV server, carry the random number (Rand) of using when generating key in the response, can also carry key and generate Transaction Identifier (B-TID).Wherein, Transaction Identifier B-TID can use base64 (a kind of 64 encryption algorithm) by GBA and generate to random number code and in conjunction with the GBA domain name, as: B-TID=64encode (Rand)@GBA_domain_name.Here, B-TID is a conversation affair mark, identifies these affairs of this negotiating about cipher key shared SNS_key, and then is different from other SNS_key generation affairs.

Optionally, the IPTV server also passes through the SNS server, send Transaction Identifier (B-TID) to SNS user place terminal, make SNS user according to this Transaction Identifier (B-TID), confirm request by its place terminal to IPTV server initiating equipment uniqueness, this request is carried user identity (User ID), current SNS user terminal unique identification (Terminal Unique ID) and key and is generated Transaction Identifier (B-TID); After the IPTV server receives equipment uniqueness affirmation request, utilize the parameters such as random number (Rand), Share_Key of the B-TID query generation shared key of carrying in this request, generate shared key SNS_key in conjunction with terminal unique identification (Terminal Unique ID).After generating shared key SNS_key, return shared key to the SNS server, and with shared key, user identity login banner L-TID one to one.Wherein, L-TID uses base64 by the IPTV server and generates and return to random number code and in conjunction with SNS RS domain name, identifies whole login process, as: L-TID=64encode (Rand)@SNS RS_domain_name.This login banner L-TID is used for the foundation that terminal is further asked shared key.At last, the SNS server returns to the SNS terminal with L-TID.

Further alternative, when having under the prerequisite of shared key Share_key at IPTV server and IPTV GBA, SNS community users login SNS server, this SNS community users identity of NSN server authentication, and negotiate shared key SNS_key with the IPTV server interaction, in negotiations process, GBA returns Transaction Identifier B-TID and confirms request to user terminal triggering terminal consistency, prevent other user's forgery attack, guarantee the one-to-one relationship between SNS user identity and this subscriber terminal equipment, thereby guarantee that follow-up use shared key SNS_key is sent to safely legal terminal with business and content-data.

Shared key SNS_key can generate when the IPTV program is watched in SNS user's request jointly in real time.The generative process of but considering this key needs larger amount of calculation, and when a large number of users asked jointly to watch the IPTV program simultaneously, huge amount of calculation may make GBA can't bear the heavy load.For this reason, generate shared key in the time of can logining the SNS system the SNS user of aforementioned IPTV user's binding, activate shared key afterwards when the IPTV program is watched in SNS user's request jointly, shared key then is in deactivation status when not watching the IPTV program.

As a kind of example, the method that below provides a kind of shared key SNS_key to generate, store and delete.

At first, the generation of shared key SNS_key.SNS_key generates in GBA, computational methods as: SNS_key=KDF (Share_key, the terminal unique identification, Rand).Here, KDF refers to cipher key derivative function (Key Derivation Function), and its concrete form can with reference to existing encryption technology, not given unnecessary details herein.Wherein, the terminal unique identification provides when being asked by SNS user, guarantees the uniqueness of shared key SNS_key; Random number is then produced and is by GBA and increases progressively trend, when guaranteeing the dynamic of shared key SNS_key, offers application server and detects whether the current SNS_Key that receives is up-to-date shared key.

Secondly, the storage of shared key SNS_key.As previously mentioned, for the operand of avoiding GBA excessive, shared key SNS_key generates when SNS user logins the SNS system, and this key is only useful when watching the IPTV program, so has defined two store statuss of shared key SNS_key in the present embodiment: state of activation and deactivation status.Described state of activation is when SNS user starts business, activates shared key SNS_key, and identifying user has added assigned ip TV program and jointly watched scene, and can use shared key to finish corresponding service and content requests; Described deactivation status refers to initiatively withdraw from or the IPTV user that jointly watched when expelling as the user, and the state of activation of shared key is cancelled, and the user can't hold this key and continue any business of request and content.The definition of above two states both can have been saved the operand of GBA, can not produce yet the user hold identical shared key repeatedly acquisition request different IP TV good friend's IPTV program jointly watch traffic issues.

At last, the deletion of shared key SNS_key.According to generating principle and the scene demand of SNS_key, can cause the factor of key deletion to have: the life cycle cut-off of Share_key inefficacy, Share_key, SNS_key inefficacy, the life cycle cut-off of SNS_key, the renewal of random number, the switching of terminal.

Need to prove, in the present embodiment, the entity that the IPTV program is provided can be media server, when issuing programme information by media server to SNS user, can activate shared key by the cipher consistency contrast, and then determine whether to send to this SNS user the programme information of this user's request.For example: when IPTV user's agreement is watched program jointly with this SNS user, then SNS user's request is watched that jointly the request of program is transmitted to media server; After media server receives service request, carry key generation Transaction Identifier B-TID and ask SNS_key to GBA, return SNS_key after the GBA identification request; Media server compares the SNS_key that the SNS_key in the SNS user terminal requests and GBA provide, if consistent, then sends success response to the SNS server; After the SNS server receives success response, activate shared key SNS_key, and it is returned to the SNS user terminal.After the SNS user terminal receives response, directly send the request of watching to media server, media server is to its distribution media stream.Use SNS_key that the content Media Stream is carried out encryption and decryption in this process.

In one embodiment, the idiographic flow that SNS user logins the SNS server comprises the steps: as shown in Figure 8

801:SNS user asks to login the SNS community system, carries parameter in the request and comprises SNS user authentication information (such as user name User ID, login password Password), SNS terminal unique identification (Terminal Unique ID).

The 802:SNS server sends key negotiation request to the IPTV server, carry in this request SNS user ID (such as User ID) and as described in the terminal unique identification.

The 803:IPTV server judges whether described SNS user is bound by IPTV user.Concrete IPTV server can be inquired about local IPTV user ID of preserving and the corresponding relation of binding the SNS user ID, if in above-mentioned corresponding relation, inquire described SNS user's user ID (for example user name User ID), then execution in step 804, otherwise, the IPTV server can return to the SNS server response of refusal key agreement, at this moment, the SNS server can continue to carry out normal SNS user's login process with aforementioned SNS user.

The 804:IPTV server generates shared key to the GBA request, carries described SNS user ID and described terminal unique identification in this request.

805:GBA generates shared key SNS_key according to the request of IPTV server.Specifically can generate shared key SNS_key according to prior and the Share_key that the IPTV server negotiate is good, described terminal unique identification and random number R and.

806:GBA generates response to IPTV server " return " key", and described SNS user ID is carried in this response, key generates Transaction Identifier B-TID and described random number R and.

The 807:IPTV server sends key negotiation response to the SNS server, and described SNS user ID and B-TID are carried in this response.

The 808:SNS server returns login response to the SNS terminal, and login banner L-TID is carried in this response.

809-813: terminal consistency is confirmed process.Wherein 811 is that the IPTV server generates consistent SNS_key according to Share_key, described terminal unique identification and described random number R and.

It will be appreciated by those skilled in the art that, in the above-mentioned flow process, terminal consistency is confirmed process and nonessential, above-mentioned steps 811 can be placed between step 806 and 807 and carry out, be that the IPTV server is after the key of receiving GBA generates response, namely generate consistent SNS_key, and to SNS server " return " key" negotiate response, this moment, the SNS server returned described login banner L-TID in step 808.

In the situation of having used secret key encryption, SNS user need to use aforesaid SNS_key to obtain the Media Stream of IPTV program.Fig. 9 has shown that SNS user uses described SNS_key to obtain the example of a flow process of IPTV Media Stream:

Step 901-905 is aforesaid step S212-S217, wherein, the SNS user terminal carries SNS user ID (User ID), IPTV user ID (Host ID) to jointly watching of SNS server transmission in the step 901 in the request, and described login banner L-TID.After step 905, this flow process also comprises:

After the 906:IPTV server carries out identity validation to the SNS terminal, transmit described jointly watching and ask to media server.

907-908: after media server receives service request, carry key generation Transaction Identifier B-TID and IPTV user ID Host_ID and ask SNS_key to GBA, return SNS_key after the GBA identification request.

909-911: media server compares the SNS_key that the SNS_key in the SNS user terminal requests and GBA provide, if consistent, then sends success response to the SNS server.

After the 912-913:SNS server receives success response, activate shared key SNS_key, and it is returned to the SNS terminal.

After the 914-915:SNS terminal receives response, the Media Stream of the IPTV program that directly will watch to the media server request, media server is to its distribution media stream.Use SNS_key that the content Media Stream is carried out encryption and decryption in this process.

Embodiment 3

As shown in Figure 3, the embodiment of the invention provides a kind of method of shared information, described method comprises step S301～S320, wherein step S301～S318 is identical with S201～S218 among the embodiment two, concrete steps and accompanying drawing are referring to embodiment 2, repeat no more, the difference of present embodiment and embodiment 2 is that present embodiment also comprises step S319～S310 herein:

S319: receive the shared ending request of IPTV program that IPTV user sends, described IPTV program is shared in the ending request and is carried IPTV user ID and SNS user ID;
